Description

Technical Field

[0001] This utility model relates to the technical field of burr removal devices, specifically a burr removal device for edges and corners. Background Art

[0002] Plastics processing developed alongside the development of synthetic resins, and the advancements in plastics machinery have mutually promoted each other. Many plastics processing technologies are derived from rubber, metal, and ceramic processing. The history of plastics processing can be traced back to the 1890s. After the invention of celluloid, due to its flammability, it could only be molded into blocks, which were then machined into sheets. These sheets could then be processed using thermoforming. Plastics processing is a general term for all processes that transform synthetic resins or plastics into plastic products. It is a major production sector within the plastics industry, generally including plastic formulation, molding, machining, joining, finishing, and assembly.

[0003] During plastic production, due to equipment defects, it is unavoidable that some burrs will be generated after molding. The usual method for removing burrs is grinding, that is, using a grinding machine to grind the burrs to make the surface of the plastic part smooth. The existing deburring method mainly involves manual hand-held grinding. Although this method can remove burrs, it can easily cause fatigue for workers after a long time. Therefore, there is a need for a burr removal device for plastic processing to solve the above problems. Thus, those skilled in the art have provided a burr removal device to solve the problems mentioned in the background art. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 In this embodiment of the present invention, a burr removal device includes a housing 1. The housing 1 has slots 2 on its front and rear sides, and slide rails 3 on the top and bottom of each slot 2. Two sliding blocks 4 are installed inside each of the two slots 2. A ball seat 5 is installed on one side of each of the four sliding blocks 4. A ball head 6 is installed inside each of the four ball seats 5. A rotary motor 7 is installed on one side of each of the four ball heads 6. A grinding ring 8 is installed around each of the four rotary motors 7. Two sliding shafts 9 are installed inside each of the two slide rails 3, and the sliding shafts 9 pass through the sliding blocks 4. First screws 10 are installed on the left and right sides of the shell 1, with one end of the first screw 10 extending to connect to the sliding block 4. The first screw 10 and the sliding block 4 are connected by an I-shaped part 11. Each of the four rotary motors 7 has a connecting block 12 installed at one end. A trapezoidal connecting block 13 is installed at one end of each of the four connecting blocks 12. Two connecting blocks 12 are connected to each trapezoidal connecting block 13. Second screws 14 are installed on the left and right sides of the shell 1, with one end of the second screw 14 extending to connect to the trapezoidal connecting block 13. The second screw 14 and the trapezoidal connecting block 13 are connected by an I-shaped part 11.

[0023] When in use, remove the size of the burrs and edges of the parts as needed, and rotate the first screws 10 on the left and right sides of the outer casing 1 to control the sliding block 4 to move back and forth.

[0024] In one embodiment, specifically, the sliding block 4 is controlled to move back and forth, thereby controlling the ball seat 5 and the ball head 6 to move back and forth, thereby controlling the distance between the rotary motor 7 and the grinding ring 8.

[0025] Among them, the screw No. 2 14 in the middle of the left and right sides of the sliding shaft 9 controls the forward and backward movement of the trapezoidal connecting block 13.

[0026] Furthermore, by connecting the connecting block 12 through the trapezoidal connecting block 13, the rotary motor 7 and the grinding ring 8 can be further controlled to move back and forth.

[0027] In one embodiment, specifically, because of the constraint of the sliding shaft 9, the sliding block 4 cannot slide, and the rotary motor 7 and the grinding ring 8 can be slightly rotated by the ball seat 5 and the ball head 6.

[0028] The rotating motor 7 and the grinding ring 8 can grind the parts that need to have their edges and burrs removed more precisely after they rotate.

[0029] The working principle of this utility model:

[0030] First, based on the required size of the parts to be deburred, rotate the first screw 10 on both sides of the outer casing 1 to control the sliding block 4 to move back and forth, thereby controlling the ball seat 5 and ball head 6 to move back and forth, thus controlling the distance between the rotary motor 7 and the grinding ring 8. Control the second screw 14 in the middle of both sides of the outer casing 1 to control the trapezoidal connecting block 13 to move back and forth. Connecting block 12 is connected through trapezoidal connecting block 13, further controlling the back and forth movement of the rotary motor 7 and the grinding ring 8. Because of the constraint of the sliding shaft 9, the sliding block 4 cannot slide. The rotary motor 7 and the grinding ring 8 can be slightly rotated through the ball seat 5 and ball head 6. After the rotary motor 7 and the grinding ring 8 rotate, the parts that need to be deburred can be ground more meticulously.
